Many of the individuals hitherto described - and certainly some who will be described in future columns - are long departed, sometimes decades ago. Perhaps few, if any of the readers here have ever encountered Tanaka Bansen, for example, or Abbe Kenshiro.
However, your own teacher might have.
One legitimate way to add to the archives here is for you to interview your teacher - with his or her knowledge, of course, and write up an account of their contact with the shihan under discussion - with the same parameters that are requirements of any of the columns. All of which is described above.

You are certainly welcome to show your instructor - or acquaintance - the column in question, and let them know how welcome an account of their experience would be.
